The defect
Porsche Cars North America, Inc. (Porsche) is recalling certain 2016-2017 911 and Boxster, 2016 Cayman and Panamera vehicles. The air bag Electronic Control Unit (ECU) may have a defective power supply capacitor that can result in air bag deactivation or inadvertent deployment of the air bags.
The risk
Deactivated air bags increase the risk of injury. Inadvertent deployment of the air bags increase the risk of a crash.
